I've allready tried that recovery mode yes and dellete all and etc etc... but it's the same... I think it's virused.. see ... I downloaded some aplications from google play and after that my phone blacked out... I hope it's not the soft...
I also downloaded a keyboard app from the Play Store and my Samsung phone just blacked out. I can't even go to recovery mode. I plan to bring my phone to Samsung to have it repaired. I suggest you do the same. Contact Acer.
